Tip 3: Realistic Alignment, Part 2: What is Autoalign Abuse?
This tip is something I was thinking of mentioning in Tip 1, but I decided it'd be worth having its own article...
If you're following the guidelines of tip 1 and trying to align your textures realistically, you will eventually come across the issue of using textures on oddly-sized lines. Thankfully, the answer is not to limit your mapping to straight lines on the 64x64 grid. Not even close.
So let's say I've got this little elbow-shaped room here, textured with TEKGREN paneling, and with a COMPSTA computer panel on each side:
I haven't done any alignment yet, but right now everything looks perfectly aligned except for that diagonal wall in the middle.
So let's just autoalign it...
Argh, that's even worse! Now all the panels to the right of the diagonal wall are wrapped around corners or cut into like wallpaper!
The trick to correctly aligning this room is to split the diagonal line into several smaller lines, and manually aligning them to stretch or squeeze the panels so that they fit the wall correctly.
You can either set it up with two skinny panels like this,
or with one wide panel like this:
Either way is correct; it's just a matter of what looks best to you on that particular size and shape of wall. Of course, for longer walls you would add more vertices to split them into more than two panels.
If you want to do a bit of math, you can figure out how many lines to split your wall into by looking at the odd-sized wall with no alignment, counting the number of panels you can see (rounding up or down to the nearest, so that if you see most of a panel, you'd include it, but if you can only see a bit of it, you wouldn't), and then split the wall into that number * 2 lines. I generally then do the manual alignment in 3D mode, but you could also use some basic math to figure that out if you prefer doing it that way.
This same technique can also be used on STARTAN, METAL2, BRONZE, PANEL, and any other textures that are composed of outlined panel shapes, and can be applied to other uses, such as fitting a 16- or 32-wide ceiling light into a TEKGREN wall and cutting the panels around it to fit.
